[0050] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0051] The present invention provides an energy-saving tunnel safety lighting control system and an intelligent control and dimming method thereof, such as Figure 1 and Figure 2 As shown, the control system includes a lighting unit 2, a remote detection unit 1, a photosensitive detection unit 3, a brightness adjustment unit, a scene detection unit 4, a storage unit, an early warning unit 5 and a central control unit.

[0052] The remote detection unit 1 is arranged at the tunnel entrance, and is used to detect and identify whether there is an object moving toward the tunnel entrance, and to feed back a signal to the central control unit, and the central control unit controls the lighting unit 2 to turn on and off according to the feedback signal. The detection range of the remote detection unit is 0.005 to 2 km (the detection range refers to the distance from the tunnel entrance in the direction away from the tunnel exit, and detects whether there is a moving object moving toward the tunnel entrance within the distance range); the feedback signal includes a first feedback signal for indicating the presence of a moving object and a second feedback signal for indicating the absence of a moving object.

[0053] The lighting unit 2 includes a lighting lamp, which sequentially forms an entrance lighting section 21, a middle lighting section 22 and an exit lighting section 23 along the direction from the tunnel entrance to the tunnel exit;

[0054] The brightness adjustment unit is used to adjust the brightness of the lighting unit and control the lighting unit to be turned on and off, and includes a first adjustment module, a second adjustment module and a third adjustment module respectively connected to the entrance lighting segment 21, the middle lighting segment 22 and the exit lighting segment 23;

[0055] The photosensitive detection unit 3 includes a first photosensitive sensor 31, a second photosensitive sensor 33 and a third photosensitive sensor 32 for respectively acquiring brightness data at the tunnel entrance, the tunnel exit and the middle lighting section 22;

[0056] The central control unit receives the first feedback signal, controls the first photosensor 31 and the second photosensor 33 to obtain the brightness data at the tunnel entrance and the tunnel exit, respectively, and calculates the target brightness of the middle lighting section 22 according to the brightness data at the tunnel entrance, the brightness data at the tunnel exit and the tunnel length;

[0057] The third photosensor 32 acquires the brightness data of the middle lighting segment, and feeds back the brightness data of the middle lighting segment 22 to the central control unit, and the central control unit controls the second adjustment module to adjust the brightness of the middle lighting segment 22 to the target brightness of the middle lighting segment 22;

[0058] The central control unit calculates the difference between the brightness data at the tunnel entrance and the tunnel exit and the intermediate lighting segment 22, and calculates the superposition coefficient or the reduction coefficient of the brightness of the entrance lighting segment 21 and the exit lighting segment 23 according to the difference between the brightness data at the tunnel entrance and the tunnel exit and the intermediate lighting segment 22; controls the first adjustment module to adjust the target brightness of the entrance lighting segment 21 according to the brightness data at the tunnel entrance and the superposition coefficient or the reduction coefficient of the brightness of the entrance lighting segment 21, and controls the second adjustment module to adjust the target brightness of the exit lighting segment 23 according to the brightness data at the tunnel exit and the superposition coefficient or the reduction coefficient of the exit lighting segment 23.

[0059] When controlling lighting dimming, the system performs the following steps:

[0060] The remote detection unit 1 detects and identifies whether there is a moving object moving toward the tunnel entrance, and feeds back a first feedback signal (indicating the presence of a moving object) or a second feedback signal (indicating the absence of a moving object) to the central control unit. When the central control unit receives the first feedback signal, the central control unit controls the first photosensitive sensor 31 and the second photosensitive sensor 33 to collect brightness data at the tunnel entrance and the tunnel exit, respectively, and transmits the collected brightness data back to the central control unit. The central control unit calculates the target brightness of the middle lighting section 22 according to the brightness data of the tunnel entrance, the brightness data of the tunnel exit and the tunnel length, and controls the second adjustment module to adjust the brightness of the middle lighting section (during adjustment, the third photosensitive detection sensor 33 is controlled to detect the brightness data of the middle lighting section 22, and the brightness data is transmitted back to the central control unit. The central control unit The brightness data is compared with the target brightness of the middle lighting segment 22 to determine whether the brightness is adjusted to the target brightness. If not, the adjustment is continued until the brightness of the middle lighting segment reaches the target brightness); thereafter, the central control unit calculates the interpolation of the brightness data of the tunnel entrance and the tunnel exit with the middle lighting segment 22 respectively, and calculates the superposition coefficient or the reduction coefficient of the brightness of the entrance lighting segment 21 and the exit lighting segment 23 respectively according to the difference between the brightness data at the tunnel entrance and the tunnel exit and the middle lighting segment 22; the first adjustment module is controlled to adjust the target brightness of the entrance lighting segment 21 according to the brightness data at the tunnel entrance and the superposition coefficient or the reduction coefficient of the brightness of the entrance lighting segment 21, and the second adjustment module is controlled to adjust the target brightness of the exit lighting segment 23 according to the brightness data at the tunnel exit and the superposition coefficient or the reduction coefficient of the exit lighting segment 23.

[0061] The system remotely collects signals of moving objects moving from the tunnel entrance to the tunnel entrance. When a moving object is detected, the target brightness of the tunnel entrance lighting section 21, the middle lighting section 22 and the exit lighting section 23 is dynamically adjusted. When no moving object is detected, the lighting unit 2 is kept off, thereby achieving energy saving. At the same time, the brightness of the entrance lighting section 21, the middle lighting section 22 and the exit lighting section 23 can be effectively and dynamically adjusted according to environmental changes, so that the entrance lighting section 21 and the exit lighting section 23 can adapt to the changes in light intensity in the tunnel, thereby improving the safety of vehicle driving.

[0062] It should be noted that the target brightness of the entrance lighting section or the exit lighting section is calculated by adding a superposition coefficient or a reduction coefficient to the brightness of the first lighting lamp to reach the brightness of the next lighting lamp, thereby realizing dynamic adjustment of the brightness of the entrance lighting section and the exit lighting section, so that the human eye has a lighting intensity adaptation process, thereby improving the safety of tunnel lighting.

[0063] like Figure 1 and Figure 2As shown, the storage unit is used to store scene data;

[0064] The scene detection unit 4 is used to obtain scene data, including a first scene detection module 41 arranged at the tunnel entrance and a second scene detection module 42 arranged inside the tunnel;

[0065] The early warning unit 5 is arranged at the entrance of the tunnel;

[0066] The central control unit compares the scene data with the stored scene data, determines whether there is danger at the tunnel entrance and inside the tunnel, and controls the early warning unit 5 (the early warning unit 5 can use a display screen, signal lights or voice broadcasts to remind the driver of the situation at the tunnel entrance and inside the tunnel ahead, and remind the user to drive safely) to issue an early warning.

[0067] When the security prompt appears, follow these steps:

[0068] The first scene detection module 41 and the second scene detection module 42 detect the scene images at the tunnel entrance and inside the tunnel respectively, and transmit the collected image information back to the central control unit; the central control unit compares the collected scene images with the scene images pre-stored in the storage unit, judges the traffic conditions at the tunnel entrance and inside the tunnel respectively, and controls the early warning unit to display or voice prompt vehicles entering or about to enter the tunnel to drive safely, thereby effectively improving tunnel traffic safety.

[0069] It should be noted that the first scene detection module 41 and the second scene detection module 42 both use a combination of infrared thermal imaging and optical visual imaging, and can collect scene images in the tunnel based on heat sources or non-heat sources.

[0070] It is worth mentioning that in order to effectively ensure the lighting safety in the tunnel, Figure 3 As shown, the lighting lamp is a light-seeing but not light-invisible lamp. The lighting direction of the lighting lamp is the same as the driving direction of the vehicle. It is set at a certain angle to the tunnel ground, so that the light irradiation direction is from the rear of the car to the front, and at the same time, it is irradiated on the rearview mirror of the car and then reflected to the ground, which can effectively avoid visual dizziness caused by the light spot on the vehicle when the vehicle is driving at high speed, and further ensure the safety of tunnel traffic.

[0071] Secondly, the control system also includes an emergency lighting lamp 6 arranged at the top of the tunnel, and the emergency lighting lamp 6 is connected to the central control unit;

[0072] The central control unit compares the scene data with the scenario data, identifies the scene in the tunnel, and controls the emergency lighting 6 to turn on in the scenario of low visibility in the tunnel to guide the vehicle out of the tunnel.

[0073] In scenarios where visibility is low, such as when a traffic accident occurs and smoke is generated, the central control unit controls the emergency lights to light up, illuminating the tunnel floor. Drivers follow the light to exit the tunnel, thereby completing traffic guidance in the tunnel to ensure tunnel traffic safety.

[0074] It should be noted that the emergency lighting is a projection lamp, the light it irradiates can penetrate smoke and other environments, thereby irradiating the ground to form route guidance signs to guide vehicles out of the tunnel.

[0075] In addition, the control system also includes a remote monitoring terminal that establishes data interaction with the central control unit through a communication module.

[0076] By using the remote communication module to establish data interaction between the system and the remote monitoring terminal, remote monitoring in the tunnel can be realized. The monitoring content may include scene monitoring in the tunnel, lighting intensity and other data monitoring; the communication module includes network remote communication and networkless remote communication (capable of control and monitoring in both networked and networkless environments, with convenient control), and the monitoring equipment can be remotely monitored using smart devices such as computers and mobile phones.

[0077] In addition, the system further comprises a visibility detector 7 installed in the tunnel;

[0078] The visibility detector 7 is used to detect visibility information and haze information in the tunnel, and feed the visibility information and haze information back to the central control unit;

[0079] The central control unit transmits the visibility information and the haze information to the early warning unit 5 for early warning, and transmits the visibility information and the haze information to the remote monitoring terminal.

[0080] The visibility information and haze information in the tunnel are detected by the visibility detector 7. After being processed by the central control unit, the visibility information and haze information are transmitted to the early warning unit 5 to prompt the vehicle driver, prompting the user to drive carefully to ensure driving safety in the tunnel. The information is transmitted to the remote monitoring terminal through the communication module for display, thereby realizing remote monitoring of the visibility information and haze information in the tunnel.

[0081] In addition, the present invention also provides a method for intelligently controlling dimming, such as Figure 3 As shown, the method includes applying the above control system to dynamically adjust the brightness of the tunnel entrance lighting section, the middle lighting section and the exit lighting section, specifically including:

[0082] S1, remote detection and identification of whether there is a moving object moving towards the tunnel entrance. If there is a moving object, S2 is executed; otherwise, detection and identification are repeated;

[0083] S2, obtaining brightness data at the tunnel entrance and tunnel exit;

[0084] S3, calculating the target brightness of the middle lighting section according to the brightness data of the tunnel entrance, the brightness data of the tunnel exit and the tunnel length;

[0085] S4, adjusting the brightness of the middle lighting segment according to the target brightness of the middle lighting segment;

[0086] S5, obtaining the brightness data of the middle lighting segment, and determining whether the brightness of the middle lighting segment reaches the target brightness of the middle lighting segment, if it reaches the target brightness, executing S5, otherwise executing S3;

[0087] S6, respectively calculating the brightness data difference between the tunnel entrance and the tunnel exit and the middle lighting section;

[0088] S7, calculating the superposition coefficient or the reduction coefficient of the brightness of the entrance lighting segment and the exit lighting segment respectively according to the brightness data difference between the tunnel entrance and the tunnel exit and the middle lighting segment;

[0089] S8. Adjust the target brightness of the entrance lighting segment according to the brightness data at the tunnel entrance and the superposition coefficient or reduction coefficient of the brightness of the entrance lighting segment, and adjust the target brightness of the exit lighting segment according to the brightness data at the tunnel exit and the superposition coefficient or reduction coefficient of the exit lighting segment.

[0090] In summary, the present invention can effectively reduce energy loss and achieve the purpose of energy saving by remotely detecting and collecting moving objects in the direction of the tunnel entrance and transmitting them in real time to the central control unit to control the opening and closing of the lighting units in the tunnel; intelligently adjust the lighting intensity of the tunnel entrance lighting section and the exit lighting section to superimpose and increase or decrease, so that the human eye can adapt to the changes in light intensity in the tunnel and the outside world, which plays a role in safe driving; at the same time, the scene detection unit is used to update the scene in the middle section of the tunnel in real time. If an accident or disaster occurs, it will be transmitted to the early warning module outside the tunnel in time through the central control unit to play a prompting role, which can effectively ensure the safety of tunnel traffic.
